spinström
Spinström, from Swedish meaning “spin current,” is a concept in condensed matter physics and spintronics describing the flow of spin angular momentum in a material without necessarily large net electric charge transport. In practice, it refers to a nonzero transport of spin polarization carried by electrons, which can propagate over a characteristic spin-diffusion length before relaxing.
Spinström can be generated by electrical spin injection, optical spin orientation, or thermally driven processes such
Detection and characterization rely on a range of techniques. Nonlocal magnetoresistance measurements, spin-pumping experiments, and time-resolved
Applications envisioned for spinström phenomena include nonvolatile memory, spin-based logic, and high-sensitivity magnetometry. Research focuses on
In Swedish-language literature, spinström is frequently used as the translation of “spin current”; in English-language contexts,
